Comic-Con 2016: 15 Biggest Reveals You Need To See
3. The Hulk Will Have Gladiator Armour In Thor: Ragnarok
Though Marvel Studios have rubbished the idea of making a standalone Planet Hulk film, there's mounting evidence that they're going to incorporate it into Thor: Ragnarok, especially now that the show floor revealed that The Hulk will wear gladiator armour for at least some of the movie.
This makes it extremely likely that, after Age of Ultron, The Hulk somehow fled to outer space, became a gladiator on some planet, and Thor tracks him down there, requesting his help to bring down the threat to Asgard.
This only enhances the likelihood that Ragnarok is going to be an extremely weird movie, and that's pretty awesome.
